SCALE.

SPECIFICATION forming part of Letters Patent No. 538,252, dated April30, 1895.

Application filed August 14,1894. Serial No. 520,335. (No model.)

To all whom it may concern:

3e it known that I, AUGUSTINE J. GASTON, a citizen of the United States,residing at Beloit, in the county of Rock and State of Wisconsin, haveinvented certain new and useful Improvements in Dairy-Scales, of whichthe following is a specification.

The object of this invention is to construct a scale, in which a foldingand swinging plat form is employed, and means for raising the scale,beam and platform in a vertical direction in order that the platform mayclear the floor so that the articles placed thereon may be weighed.

In the accompanying drawings,Figure 1 is a side elevation. Fig. 2 is anend elevation. Fig.3 is an end elevation of the platform and itssupporting rods in their folded position. Fig. 4 is a facerepresentation of the base plate. Fig. 5 is a vertical central sectionthrough the same. Fig. 6 is a transverse section 011 dotted line a, Fig.4. Fig. 7 is atransverse section on dotted line b, Fig. 4.

The base 1 is of rectangular form, having a pair of lugs 2 extendingfrom its upper portion, and a pair of lugs 3 extending from its lowerportion. Beneath these lugs and against the face of the base is locateda movable support 4. The upper pair of lugs are each provided withrecesses 5 and 6. In the former is located a roller 7 and its axis ofrotation lying in a horizontal plane at right angles to the face of thebase, and in the recess 6 is located a roller 8 its axis of rotationalso in a horizontal plane but at right angles to the axis of the roller5. The rollers 7 are so located as to engage the edges of the movablesupport 4 and the rollers 8 engage its front face. The lower pair oflugs 3 each has a recess 9 in its overhanging lip within which is placeda roller 10 which moves in contact with the edge of the movable supportnearits lower end. A recess 11 is formedin the face of the base betweenthe lugs 3 and within this recess is located a roller 1 2 its axislocated in a plane transverse of the base and against which the rearface of the lower end of the movable support rests or moves in contactwith.

To the lower end of the base is pivoted an eccentric 13 having a handle14 by means of which the movable support may be elevated from theposition shown in solid lines at Fig.

4 to the dotted line position shown in same figure, and the rollerengagement with the movable support permits of its easy slidingmovement. From the front face of the movable support extends a bearing15 and into an opening in the support is placed the movable portion 16having its face in semi-circular form. The outer conformation of thismovable portion is of U edge form which fits the opening. Near the lowerend of the movable support is located a bearing 17, and into an openingformed in the support is placed a step block 18, having its outersurface tapering and having a projection extending from its lowerportion. That portion of this step block lying within the bearing hasits face in semi-circular form. A bracket 19, is provided with twoprojections or pintles 20 and 21,the former held in place in the bearing15, and the latter in the bearing 17, so that a pivotal connection isformed between the bracket and movable support the weight of the bracketbeing sustained by the step block 18. To the free end of this bracket ispivoted an arm 22, by the pin 23. This arm supports a double scale beam24, the direction of both bars being the same but the weights employedbeing of difierent hefts, that is, sixteen to one, in order thatthelarger weight will indicate pounds and the smaller one ounces.

From the scale beam at one end is suspended a bar 25, its other endsuspended from the free end of the bar 22, and to this suspended bar isconnected the platform upon which the article to be weighed is placed.This platform 26, has bails 27, and 28, pivotally connected to a link30, at one end its other end pivotally connected to link 31, having itsupper end in hook form which engages a loop connected to the suspendedbar 25. To the link 30, between its pivotal connection with the bail 27and link 31 is pivotally connected a link 33 at one end, its other endpivotally connected to the ears of the bail 28. By means of these linksa connection is formed between the bail and suspended bar. To the upperend of the link 31 is pivoted a hook 84.

When the scale is in use the parts will appear as shown at Figs. 1 and2, the box being secured in a position to allow the platform to restupon the floor. The article is placed upon the platform and by means ofthe eccentric lever 14 is turned into the position shown in dotted linesat Fig. 4 which will cause the platform and the article placed thereonto be raised clear of the floor. Through the connection of the platformwith the movable support 4, after the article has been weighed theplatform is lowered in contact with the floor in order that the articlemay be easily removed therefrom; and when the scale is not in use, theattendant raises upon the bail 27 which will cause the other bail andplatform to assume the position shown at Fig. 3, when the hook 34 willengage a flange on the outer surface of the bail, holding the partsfolded, when the arm 22 in its connection with the bracket 19 and thebracket in its connection with the movable support will allow thefolding of the parts into a small space I claim as my invention- 1. In ascale, a stationary base standing in a vertical position having twopairs of cars extending from its face, each ear of the upper pair havingtwo recesses and within each is located a roller, each ear of the lowerpair having a recess supporting a roller, the stationary base having arecess in its face near the lower pair of ears, a roller located in therecess and a movable support held in position in a slidable manner bythe various rollers.

2. In a scale, a support, a scale beam connected therewith, a platformhavinga connection with the beam, two bails having apivotal connectonwith the platform, one bail having a linked connection with the scalebeam and the other bail having a detachable connection with the linkconnection in such a manner that the platform may be folded into avertical position.
